Efficient quantum transport in disordered Floquet networks
Hlér Kristjánsson, Jonathan Brugger, Gabriel Dufour +2
We propose a mechanism for fast and efficient quantum transport through disordered networks with variable on-site energies, inspired by photosynthetic complexes. The mechanism reli…
Two-particle tunneling and the impact of interaction
Jonathan Brugger, Christoph Dittel, Andreas Buchleitner
We analyze the tunneling of two bosons in a double-well, for contact, soft-, and hard-core Coulomb interaction of tunable strength. Transitions from correlated to uncorrelated tunn…
Many-body quantum non-Markovianity
Jonathan Brugger, Christoph Dittel, Andreas Buchleitner
We port the concept of non-Markovian quantum dynamics to the many-particle realm, by a suitable decomposition of the many-particle Hilbert space. We show how the specific structure…
Output statistics of quantum annealers with disorder
Jonathan Brugger, Christian Seidel, Michael Streif +3
We demonstrate that the output statistics of a quantum annealing protocol run on D-Wave 2000Q can be explained by static disorder garnishing an otherwise ideal device hardware. A B…
